I also want to add that his bedroom should be as free as possible of any lights, except a dim nightlight. On my sons CD player for his bedtime music (which is put on repeat, so if he does wake up he will fall back asleep, this also helps because after he goes to bed, we can make a little noise in the house and it doesn't bother him...) we put black wire tape over the lights so they don't show.

And we had to fine tune his schedule repeatedly over time, too. Originally his bedtime was 10PM, and we'd slowly move it back as he got more used to the routine and more willing to accept it.

My son's school offered me something similar to this during Kindergarten. I did, however, turn it down (My husband is in the military and rarely home, so I wasn't comfortable having a stranger in the house with me alone and my dog would make too much noise the entire time). I do not believe they come in and spend the night, rather, every night help create a bedtime routine and give extra support for parents to get the children into bed and stay there. And at first, probably monitor the nighttime routines to see what is wrong and what needs to be improved on.

Instead, we were given a strict guide to follow every night. Granted, it took a loooong time (almost 2 years!!) before he mastered everything. He's now at the point that he goes to bed at his bedtime without very much fuss. He takes his medications, Clonidine, (and actually knows what they do!) and he sleeps through the night. Thing is, regardless, he needs to take sleep medication - but bedtime was always bad even with the medication because he's in this gogogo 24/7 mode, where, even with the sleep medication, he couldn't fall asleep and stay asleep. But, between a solid bedtime routine AND the medication, my child actually sleeps now!

And I will tell you, I also have to take sleep medication (Trazodone-a non-habit forming sleep aid). And if I take it and do not lay down, within 15 minutes, it doesn't even make me sleepy. But if I lay down within 15 minutes of taking it, I fall asleep within 10 minutes, if that.

Anyhow, our bedtime routine is;
From the minute we start this, all lighting is dimmed in the rooms we're in.
7:30PM: No more TV, video games, computer - quite play time. (Legos, etc)
8:00PM: Bath (Fri-Sat) or shower(Sun-Thurs), lavender oil rub, vitamins (all chewable stuff), Brush teeth
8:30PM: Relaxing Yoga/Meditation while listening to calming music.
8:45PM: Read a book.
9:00PM: Take Medication with Sleepytime tea.
9:15PM: in bed with soft piano/nature sound music.

We adhere to this schedule very strictly. This is probably the only extremely strict schedule out of everything in our lives. It was very difficult at first. Not only did he fight it, but as adults, we were not used to something so rigid either. Each month it got easier and easier. But almost immediately, we saw an improvement in his sleeping habits. It wasn't until this year that I finally told him what the sleep medication was for. Previously, I told him it made him feel better - because if he knew I was trying to make him sleep, he would have fought that, too. Now, 2 years later.... he is in bed at 9:15 and asleep by 9:30 with no issues. But, if we don't follow this pattern, he won't sleep still. I tried to stop using it on the weekends, and guess who was awake until 4AM before he took a 2 hour nap???

Thank you, @A MyAutismTeam Member. I've previouslyread the Sleep Tool kit info, but it's definitely worth rereading. The others were new to me! I appreciate your answer!
